SPECIFICATION forming part of Letters Patent No. 406,971, dated July 16, 1889.

Application filed February 26, 1887. Serial No. 229,069- (No model.)

To all whom it may concern:

Be it known that we, ROBERT ll. THOMPSON and SILAS ll. \VILsON, of Brooklyn, in the State of New York, have invented a certain new and useful Improvement in Machines for Manufacturing TVrappers for Bottles, &c., of which the following is a specification.

Ve will describe a machine embodyingour improvement, and then point out the various novel features in the claims.

In the accompanying drawings, Figure 1 is a plan or top View of apart of a machine embodying our improvement. Fig. 2 is a plan or top view of the other part of such machine. Fig. 3 is a side elevation of the part of said machine which is illustrated in Fig. 1. Fig. at is a side elevation of that part of the machine which is illustrated in Fig. 2.

Fig. 13 is a side elevation illustratingamodification of a portion of the machine. Figs. 1, 2, 3, at, 11, and 12 are drawn to a scale one half of that of the other figures.

Similar letters of reference designate corresponding parts in all the figures.

The framing of the machine may be of any suitable character and made of any appropriate material. It will consist, essentially, of side frames and intermediate connecting stretchers. The frame of the machine may of course be made in sections lengthwise of the machine, and these sections maybe bolted together and separated at pleasure. This will be advantageous in reference to setting up or removing the machine.

A designates a roll, upon which a strip of corrugated paper or like material is wound. This roller is supported in bearings, from which it may be removed to permit of the substitution for it of another, as occasion may require. Preferably the strip of corrugated paper will have secured to one side of it a strip of plain paper, so that it will be in fact a combined strip made up of a strip of corrugated paper and a strip of plain paper. It is thus represented in the drawings. It is marked 13 in the drawings.

The strip of material B passes from the roll A between two guide-rollers C C and thence over a bed D, which is supported by the frame of the machine. The corrugated strip is uppermost. After leaving the rollers O C it passes between guides E E which are secured to the bed D adj ustablyin the present instance by means of screws passing through slots that extend widthwise of the 111achine-thus providing for the adjustment of the guides at different distances from the longitudinal center of the bed. Thus provision is afforded for different widths of material. These guides E E direct the material to creasing-wheels F F F which are arranged upon a shaft F, which may be driven .by a belt on a pulley with which it is provided. These creasing-wheels crease or score the material longitudinally upon lines along which it is to be folded. These wheels are provided with hubs fitting the shaft F, and secured thereto by means of set-screws pass ing through them and impinging against the shaft. The wheels are therefore adjustable lengthwise of the shaft, so as to afford provision for creasing material at different points. This adjustment is necessary for operating upon materials of dilferent widths. If desirable for any reason, a greater or less number of such wheels may be used.

Beneath the creasing-wheels is arranged a roller R, which is covered with india-rubber or analogous material. The creasing-wheels, in conjunction with this roller R, control the speed at which the material B travels, and cause it to travel at a uniform speed. For this purpose the creasing-wheels and the roller R may be regarded as a pair of rollers. After leaving the creasing-wheels the material passes through such slots.

between two folders G G These folders converge from the ends which are the nearer to the creasing-wheels toward the other ends. Their adjacent sides at the ends which are the nearer to the creasing-wheels are flaring or wider at the upper edge than the bottom edge, as may be clearly understood by reference to Fig. 7. This flare gradually decreases toward the ends which are distant from the creasing-wheels, and entirely disappears at these ends last named. Therefore as the material passes over the bed D, between the folders G G its portions which are laterally beyond the creases produced by the outer creasing-wheels F F will be gradually folded upward, until at the time of passing beyond these folders they will occupy a position at right angles to the intermediate or central portion of the material. This may be clearly understood by reference to Fig. 8. During the passage of the material between the folders G G itscentral portion, which remains unaffected by the folders, is held down upon the bed by holding-wheels H H H H.

The holding-wheels H H are affixed to a rotary shaft H and the holding-wheels H H are mounted upon a rotary shaft H These wheels are adj ustably secured upon their shafts by means of set-screws or otherwise, so that their positions may be varied for materials of different widths. Obviously any number of these wheels may be employed, as circumstances may render necessary. The shafts of these holding-wheels are supported in bearing-blocks, which may be adjusted, to cause the wheels to act with different pressures, through the agency of set-screws h h or other suitable means. These holding-wheels may rotate as the material passes beneath them- The folders G G are secured to the bed D, so that they may be adjusted widthwise of the machine. As shown, they are provided with slots extending widthwise of the machine and are secured in place by screws passing The adj ustability of the folders adapt-s them for use with materials of different widths.

Beyond the folders G G are other folders G G. These folders are supported upon the bed D. The folders G l have inwardly-extending flanges g at the upper edges of their inner or opposite sides. At the ends of these folders G G which are the nearer to the folders G G these flanges g 9 have but a slight projection and are quite high up; but said flanges increase in projection toward the other end of said folders G G and extend downwardly close to the bed D. The construction of the flanges may be clearly understood by reference to Figs. 9 and 10. In passing between the folders G G the portions of the material which were beyond the outer creases and which were turned into upright positions by the folders G G are folded downwardly against the intermediate or central portion of the vmaterial, as shown in Fig. 10.

The folders G G are secured to the bed in the same manner as the folders G G and have a like purpose.

The material B operated upon is not in contact with the bed while passing between the folders G G, although the bed sustains it. Meanwhile above the bed, between these folders G G, an endless belt or carrier I passes. It is supported and driven by rollers I 1 which may have motion imparted to them by abelt or other means. The upper portion of this belt travels along the bed in a direction away from the folders G G" and returns under the bed in the reverse direction. The material 13 is in contact with this belt during its passage between the folders G G, and is carried forward by the belt.

J designates a roller mounted removably in bearings at a considerable distance above the bed D. 011 this rollera strip K of plain comparatively thin paper is wound. This strip is intended to unite the meeting lateral edges of the strip of material folded as aforesaid. One of a number of rollers J may be substituted for another, as occasion may require. The strip K, after leaving the roller J, passes around the guide-roller J and thence over a roller J of paste or other adhesive material, and has combined with it a doctor-roller J 4 for removing superfluous adhesive material from the The roller J rotates in a tank J I ing the roller J 2 the strip K passes around the guide-roller J and is therebyforced against the meeting edges of the folded material B. Thence the material 13, with the strip K applied to it, is moved along by the endless belt or carrier 1, over the bed D, and beneath a series of drying-rollers L' L L L L L ,which are preferably heated by steam-pipes and driven by belts or other means. There may be any desirable number of drying-rollers, according to the speed at which the material B with the applied strip K is moved along.

The drying-rollers L L L L 'L L are journaled in adjustable bearings, so that they may act upon the material passing under them with any desirable pressure.

The portion of the bed which is beneath the drying-rollers L L L L L is made in the form of a hollow chest d. At intervals between the rollers L L L L L hollow bridges d extend above the path traveled by the material. Steam circulated through the chest at and hollow bridges d aids in drying the adhesive material, whereby the strip K is secured to the material 13. v

It is not absolutely essential for us to use the steam-chest-d in the bed D in connection with the other parts of the machine. We may also omit the steam-bridges d. Indeed, the

rollers L L L L L L may be omitted, if

desirable. In such case we shall prefer to substitute for them rotary brushes, journaled and arranged in the same manner as the rollers, but rotating at an increased speed. Of course we may rotate the said rollers when we use them at any speed which may be found desirable. If caused to rotate atsuch speed that their circumferences will travel faster than the material B with the applied strip K, they will operate with an ironing or rubbing and smoothing action.

Just beyond the roller L are arranged knives O O. The knife is stationary; but the knives O are fixed to a revolving head or support, one being arranged on each end of the latter. As the knives O. revolve, they periodically move into proximity with the stationary knife 0, and in conjunction there with cut the finished material transversely, thereby severing it into short pieces suitable for wrappers of the kind illustrated in Fig. 12. The head which carries the knives O is rotated by a train of gear-wheels 0 o o 0. The gear-wheel is affixed to one of the journals of the revolving head and the gear-wheel 0 to one of the journals of the pulley 1 around which the belt I passes, and the gear-wheels o o are intermediate and supported by studs on a swinging frame a. The frame a is hung at one end on the shaft which carries the pulley I and at the other end is supported by a bolt or screw 11', which passes through a slot in said frame and enters one of the side pieces of the main frame of the machine. Provision is afforded for adjusting this frame, in order that gear-wheels of different sizes may be employed for the purpose of varying the number of revolutions at which the knives 0' will be revolved in a given time, and, hence, the periods at which the finished material will be subjected to the operation of the knives, the latter being caused to travel at a uniform speed by the creasing-wheels and the roller R. Thus wrappers of greater or less length may be produced.

Motion may be imparted to the revolving head carrying the knives O by means of a belt applied to a pulley arranged upon one end of the journals of the roller I Through the train of gears just described motion will be imparted to the belt I.

here we have spoken of belts and pulleys for driving different parts of the machine we desire to have it understood that these belts maybe of any desirable material, even chain, and that when made of chain the pulleys with which they work will be made in the shape of sprocket-wheels.

Instead of the mechanism shown in Fig. 3 for pasting the strip K and directing it to the meeting edges of the folded material B we make this mechanism such as is shown in Fig. 13. In this figure J designates a roll, around which the strip K is wound. This roller is mounted in bearings, so as to be removable at will, in order that another similar roller may be substituted for it. From the roller J a strip K passes around a roller J and thence over a roller J which rotates in a tank J containing paste or other adhesive material. A doctor-roller J removes superfluous paste from the roller J and also distributes the paste upon the strip K. Beyond the roller J the strip K passes around a roller J, thence around a roller J thence around a roller J and finally around a roller J The roller J directs this strip to the meeting edges of the material B. The advantage of this particular mechanism over that shown in Fig. 8 consists in the provision which it affords for the setting or partial drying of the paste before the strip K reaches the material B.

\Vhat we claim as our invention, and desire to secure by Letters Patent, is
